‘Bone of my bones and flesh of my flesh’ in Gen 2:23

The phrase ‘bone of my bones and flesh of my flesh’ (Gen 2:23) was used to denote a family or ‘flesh and blood’ relationship (cf. Gen 29:14; Jud 9:2; Heb 2:14).  Thus, Eve was both Adam’s sibling (sister) and his wife, as they shared the same father.  This is a theme which runs throughout Scripture.  Sarah was Abraham’s wife and half-sister, through sharing the same father.  The bridegroom of Song of Solomon makes several references to ‘my sister, my bride’ (Song 4:9, 10, 12; 5:1).  These types pointed forward to Jesus, who is both the elder brother and bridegroom of the ecclesia (Rom 8:29).
